I completely concur with my noble friend that it is critical that we get to the bottom of what has happened to have generated this outbreak of cryptosporidium. It is currently far too early to know the exact cause of the outbreak. South West Water is continuing its investigations to confirm the source of the contamination. The Drinking Water Inspectorate has initiated its investigation into the cause, extent and actions of the company and begun collecting evidence on site. I should point out that it is the Drinking Water Inspectorate which is taking the lead on this investigation.
